It is not because it is sensitive to sounds that it feels uncomfortable for people who make sounds of "Kuchakucha" and chewing while eating "sound hatred syndrome (MisophoniaIt seems to be because it suffers from a disorder called "). MisoFonia is an obstacle that reacts very sensitively to every sound of everyday life, according to the latest research it turned out that the human brain of MisoPhonia is a different brain wiring than usual.

The research results on the latest brains of mythophonia are biologically relevant academic journals on February 2, 2017Current BiologyIt was announced above. In my research, he searched the brains of 20 missing persons and 22 missing persons. In the study, all subjects were asked to listen to "unpleasant sounds such as" screeching sounds ", neutral sounds such as" rain sounds "," trigger sounds "such as" chewing sounds "or" breathing sounds " I listened to and studied changes in the brain using MRI and others.

As a result of the investigation, all the subjects did not like the so-called "screeching sound" such as "screeching sound", but when hearing "trigger sound", MisoFonia heard that he began to sweat and the heart rate began to rise . When examining the change of the brain when this misoferonia listened to "trigger sound" by MRI, "brain" front part known as "part affecting what people pay attention"Islet cortexIt is clear that active activities are carried out. In addition, the anterior islet cortex of Misophonia is connected to many areas of the brain than usual, which proves that this causes an overreaction to the sound of Mithofonia.

MisoFonia is a fairly rare obstacle, but by knowing how the brain produces emotions it is possible to find a better treatment.
